# DeFi protocols eliminate institutional trust requirements but shift attack surface to off-chain human coordination layer

The Drift Protocol $270-285M exploit was NOT a smart contract vulnerability. North Korean intelligence operatives posed as a legitimate trading firm, met Drift contributors in person across multiple countries, deposited $1 million of their own capital to establish credibility, and waited six months before executing the drain through the human coordination layer—gaining access to administrative or multisig functions after establishing legitimacy. This demonstrates that removing smart contract intermediaries does not remove trust requirements; it shifts the attack surface from institutional custody (where traditional finance is vulnerable) to human coordination (where DeFi is vulnerable). The attackers invested more in building trust than most legitimate firms do, using traditional HUMINT methods with nation-state resources and patience. The implication: DeFi's 'trustless' value proposition is scope-limited—it eliminates on-chain trust dependencies while creating off-chain trust dependencies that face adversarial actors with nation-state capabilities.
